30 Claims. (Cl. 273-1011) The invention 'aims to provide a new andimproved shooting gallery in which a flash of light is projected fromagun upon pulling of the trigger, to operate a signal if the aim beaccurate. through the instrumentality of a photo-eledtric cell andamplifier.

Another object is to provide novel means for driving a traveling targetuntil the gun trigger has been pulled a predetermined number of timesand for then discontinuing operation of the entire gallery. The targetdriving means and the bulb illuminating means are preferably initiallyconditioned for operation by means of a r coin switch and the personshooting is permitted to fire a predetermined number of shots for thecoin he inserts.

A still further object is the provision of unique means for breaking thebulb circuit a fraction of a second after illumination of the bulb,preventing the user from making attempts to focus the light beam uponthe photo-electric cell after a shot has been fired.

A still further object is to makeprovision for moving the target portionat which the gun was aimed to a struck" position if the aim be accu-'rate.

Yet another object is to associate a plurality of electrical units in anovel and advantageous way. to attain the desired ends. With theforegoing in view, the invention resides in the novel subject matterhereinafter described and claimed, description being accomplished byreference to the accompanying drawings. Fig. 1 is a perspective Viewshowing the traveling target, its driving means and its supporting base.The motor is shown mounted upon this base and while various otherelectrical units used in carrying out the invention may also be mountedupon said base, they have been omitted from Fig. l for clearness.

this view being shown from a point opposite that from which Fig. 1 isviewed. I

Fig. 3 is a. vertical transverse sectional view through the upperportion of the traveling target showing one of the movably mountedtarget dropportions, the photo-electric cell associated therewith, andthe means for effecting movement of said target drop portion to a.struck" position if the aim of thegun be so accurate as to causethelight flash to strike thephoto-electric cell. a

Fig. 4 is a diagrainshowing the gun, the target,

the various electrical units and the preferred wiring.

The gallery includes a gun 45 having an electric light bulb 46 and alens 41 for projecting a beam of light toward a target. In the presentdisclosure, this target is of, the traveling type and is provided with aplurality oftarget drop portions 8 which may simulate ducks, said targetdrop portions being pivoted at 49 upon bases which are secured to anendless belt 5!. Belt 5! is trained around pulleys 52 and 53 whoseshafts 54 and 55 are suitable mounted upon a base 58. An electric motorM is mounted on. the base 55 to drive one of the belt pulleys to effecttravel of the target dr'op portions 48 and in the present showing,pulleys 5'! and 58, a belt 59 and a transmission 60, transmit power fromsaid motor M to the shaft 55. Each target drop portion (8 is formed withan opening BI and mounted on the base fill behind said opening, is aphotoelectric cell 62. If the person practicing directs the light flashfrom the bulb d6 through the opening 6| against the cell 62, the targetdrop portion 48 associated with said cell, drops, and at the same timean additional signal may be operated,

all of which willbe hereinafter fully explained.

Each base 53 carries contacts 63 for its cell 62 and said contacts areco-operable with fixed contact rails Ed and with other means hereinafterdrop electro-magnet 69 is provided to swing saidarm 51, causing rail 68to strike or move the arm 65 and cause 'the target drop portion 48 todrop; The electro-magnet 69 becomes energized only when the flash oflight from the bulb 46 is so accurately aimed as to strike thephoto-electric cell 62.

In addition to electrical contrlvances so far mentioned, various otherelectrical units and wiring therefor are employed and'will now bedescribed, and said units may well be mounted on the'base 56.

T denotes a coin slot starting switch located at the shooting post H,for bringing the motor M into play to drive the target, and forpreparingthe entire gallery for operation.

. gun 45 and serving primarily to illuminate the l3 refers to a normallyopen shot limit switch which controls the number of shots which may befired" upon insertion of one coin in switch 18. This limit switch 13includes a series of contacts I4, a contact arm 15 co-operable with saidcontacts, ratchet means I8 for advancing said arm 15- step by step alongthe contacts I4, an actuating coil C for actuating said ratchet means15, a detent 11 for holding said ratchet means after each operationthereof, a reset coil C for releasing said detent I1, and a spring 18for moving the contact arm 15 to a closed starting position when detentI1 is released.

The reference character A, denotes a two pole relay which standsnormally open; .B has reference to a three pole relay'which also standsnormally open; and C refers to a third and normally closed relay.

' l9 refers to a photo-electric relay and 80 to photo-electricamplifying means. T denotes a transformer, 8! refers to a rectifier and82 indicates a thud sounder for imitating the report of a gun. 83denotes a bell and 84 a transformer therefor, both optional.

The various electrical units above described are operatively connectedwith each other and with two current sourcesfi volt D.-C. and 110 voltA. C., by means of wiring to which the numbers l-to 42 have beenapplied. All of the wiring will be clear from Fig. 4 and the followingexplanation of operation, without encumbering the description with anindividual statement concerning each wire and such surplusage istherefore omitted. I

When the device is not in. use, all parts stand as seen in Fig. 4, thecontact arm of limit switch 13 being then beyond'the series cfcontacts'14. When a person wishes to use the device, the first vact is theplacing of coin in coin lll, along wire I to 'i to 8 through actuatingcoil of relay A along wire 8 to ill through reset coil '3 in shot limitswitch, along wire H back to 6 volt source. When coil C is thusenergized, it releases detent TI and spring 18 swings contact arm 15 tothe closed starting or home position" seen in dotted lines in Fig. 4.The current through the actuating coil of relay A causes the circuits tobe completed across contacts which causes current from 110 volt sourceto fiow from wire IE to l8 through relay contacts to I! to 20 throughprimary coil or rectifier to 2| to 22 to 23 to 11 to 110 volt source.Wire 24 connects to'wire l9 2il which connects to motor nects totransformer T allowing current to flow through primary winding oftransformer T to M allowing current to fiow throughmotor to wire2l-22-23-ll to 110 volt source. From wire 24 current also flows to wire25 whichcon 23 to l1 to source.

lead to photo-electric relay I9. This current' current from transformer'I" at wires 35 and 36.

, takes place. If. the aim is such that the flash of lightfrom bulb 46contacts photo-electric cell magnet 69 to 42 to I! to source. If bell 83and transformer 84 are connected, the flow of curdoes not flow, however,until relay I! is closed by photo-electric cell 82 through amplifier 88,etc.

summarily then, the placing of coin in slot switch Ill returned shotlimit switch to "home position closed relay A, which put rectifier 8! inservice, started motor M which started target moving, and provided a 6volt A. C. source of It might be well to point out that while theoriginal actuating current for relay A comes from 6 volt source, as soonas rectifier 8| begins to operate and shot limit switch 13 is in homeposition", relay A is held in closed position by the current from saidrectifier 8| until current is interrupted by shot limit switch 13.

The gallery is now ready for the actual shooting operation. When triggerswitch '12 on gun 45 is .pulled, current flows from rectifier 8| alongwire l2 to I to 4, through trigger switch 12 to 3 through actuating coilC in shot limit switch" to 28 to 28 through actuating coil of relay B to29 to 30 to l3 to source. Energizing coil C in shot limit switch 13, aspreviously explained, moves contact arm 15 one position.

Closing of relay B completed 3 circuits thus:

1. From 6 volt A. C. source at transformer T cur- C to 32 acrosscontacts in relay B to 3i to 38 to i3 to source. 3. From 6 volt source.at transformer T along 35 to 38 through actuating coil of thud sounder82 to 38 across contacts at relay B to 3! to 36 to source.

The first of these three newly completed circuits illuminates the lightin gun 45. The second, causes relay C toppen, breaking circuit to thelight 45. The fact that relay C is so adjusted as to cause it to operatea fraction of a second slower than relay B allows light to flash for aninstant only. The third of these circuits completedcauses the thud tosound. If the aim of the gun has not been accurate no further action 6'!current flows from amplifying unit through cell 62 and rails 64 causingphoto-electric relay;

19 to operate. This allows volt A. C. current from contacts at relay Ato flow along wire 40 through photo-electric relay l9 to M through rentinthe primary of transformer 84 is simultaneous with that in coil 69,and causes bell 83 to sound when the drop 48 falls.

When the trigger of the gun has been pulled ten times, the contact armof shot limit switch 13 no longer completes circuit 14 to IE. Breakingthis circuit causes relay A to break 110 volt circuit which causesrectifier 8! to cease functioning, motor M to stop and transformer T tocease operation. The gallery then is "dead ready for another sequence ofevents as just described. It will be observed that the energy for theac-' tuation of thetarget drop mechanism and of the audible signal 83comes from an outside source of 110 volt alternating current through acircuit including the lines l5 and II. It will be further observedthatthis circuit is controlled by the relay I8 which is energizedfromthe amplifier 80. When I use the term actuate in the speciordinarygun is used, the only connection between the gun and any other part ofthe mechanism is the light flexible electric' cable which terminates inthe gun mechanism. The gun can be laid down, picked up, moved around,manipulated without any reference whatever to any of the working workingmechanisms outside of the gun.

The switch and trigger combination in the gun is so set up that a singlepull on the trigger causes a single flash of light only to be projected.

Whether the operator holds the trigger or not makes no difference.Nothing but a single flash is projected, as distinguished from acontinuous beam, so that if the gun is not aimed at the target at theinstant the flash is projected, subsequent' correction of the aim makesno difference. It is I this flash arrangement and this entireportability of the gun which makes my device different from othernon-bullet target shooting devices because it enables the user todoexactly what he would.

do if he were firing a bullet.
